4 AnswersXbox6 years agoHow to calculate time of a falling body with gravity?
Say an object is falling in earth's gravational field and travels a distance of about 9.8 meters by which time its velocity would be about 13.8 m/second. Now imagine it hits an object below and its velocity is reduced to 8.9 m/second. How would you calculate the object's velocity if it fell another 9.8 meters if its velocity was now 8.9 m/second?
2 AnswersPhysics6 years agoWhat will the acceleration of this ball be upon impact?
If a ball with a mass of 10kg is falling at 9.8 ms-2 due to gravity and it hits a stationary ball floating in mid-air with a mass of 1kg what will the acceleration of the larger ball be upon impact? Basically how much will it have slowed by.
1 AnswerPhysics6 years agoHow do the molecules in the thermosphere emit more radiation than they absorb?
Solar radiation at the top of the atmosphere is 1367 Watts per square meter which if absorbed by a blackbody gives a maximum temperature of 121C and yet molecules in the thermosphere apparently reach temperatures of 2500C. How is this possible?
